{"product_id":"3-5-down-pipe-for-gm-duramax-l5p-6-6l","title":"3.5\" Down-pipe for GM Duramax L5P 6.6L","description":"The GM Duramax L5P 3.5\" Down-pipe is designed as a direct bolt-on replacement for 2017-2026 Chevrolet Silverado and GMC Sierra 2500HD\/3500HD trucks featuring the 6.6L Duramax L5P engine. Constructed from premium 3.5-inch T409 stainless steel, this downpipe enhances exhaust flow efficiency by an estimated 20% over stock, reducing backpressure and restriction. It completely removes the factory Diesel Oxidation Catalyst (DOC) for improved turbocharger performance and exhaust gas evacuation.\n\nIt features a secure 4-bolt flange design with two installed studs and includes heat wrap for optimal temperature control and improved heat retention, contributing to longevity. The design is ideal for high-performance applications and intended for diesel truck owners and mechanics seeking a specifically engineered solution for the L5P platform.\n\nPlease note that this Duramax L5P downpipe upgrade is intended for off-road use only and necessitates custom tuning for optimal performance and functionality. Minor adjustments may be required for 2020 and newer models.","brand":"TunerDepot","offers":[{"title":"Default Title","offer_id":52689462853944,"sku":"EP-GM-L5P-DP","price":357.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687740770.webp?v=1784906797","url":"https:\/\/store.motormia.co\/products\/3-5-down-pipe-for-gm-duramax-l5p-6-6l","provider":"MOTORMIA","version":"1.0","type":"link"}
